A new species of Entomobrya Rondani: E. tristriata sp. nov., from Jilin, one province the Northeast China and first record Entomobryoides sotoadamesi Jordana, Potapov & Baquero, 2011, are herein described. nov. is characterised by three longitudinal dark blue stripes Th. II to Abd. III, prelabral smooth chaetae larger subapical tooth on mucro. However, in most Entomobrya, ciliated subequal apical one. was described Far East Russia Chinese specimens agree with original description.

Two new species of Homidia are described here. nigrifascia sp. nov. is characterised by dark pigment on Abd. II−III and posterior part IV. obliquistria can be identified its colour pattern, chaetae ventral side head many macrochaetae Illustrations provided for both species. This the first report from Guizhou Province, China.

Two new species of Homidia are described from Eastern China: H. hangzhouensis sp. nov. and wanensis The former is characterised by smooth chaetae e l1 on labial base, two irregular transverse stripes Abd. IV, absence blue pigment Ant. I−II presence III−IV, 7−9 macrochaetae IV posteriorly 24−34 inner spines dens. latter can be identified reduced body pigment, chaeta base having some posterior modified, appearing leaflike, 8−9 83 dens.

Ecology and habits of the genus Paragavialidium are discussed. islandium Zha Wen sp. nov. is described illustrated with photographs compared similar taxa. A taxonomic review provided a key to total 12 species given.

A new species, Homidia linhaiensis, from East China is described. It separated the other members of genus by following combination characters, body colour pattern, presence 5+5 lateral macrochaetae on Abd. III, a pair extra dorsal (A2) anterior part IV and 9 smooth setae flap ventral tube. table characters closely related species provided.

Abstract The morphology of an organism is limited by genetic and environmental factors, the precise mechanism inconsistent between species. Tetrix japonica Bolivar, 1987, a widely distributed pygmy grasshopper in East Asia. However, population clustering relationships bioclimatic factors have not been previously investigated. Here, 32 geographic populations were sampled from China, morphometrics multiple statistical analyses applied to detect relationship factors. results suggested that T....

Two new species of Homidia are described from Yandang Mountain, China: H. yandangensis sp. nov. and quadrimaculata The diagnosed by their unique colour patterns, the number macrochaetae on areas A8-10 abdominal segment IV, relative position specialised microchaetae/specialised ordinary chaetae I chaetae/macrochaeta m3 V. Specimens two localities differ in macrochaeta a5 area A9 IV. Descriptions subadult dorsal thoracic chaetotaxy a key to Zhejiang Province provided here.

A third species of the genus Sinhomidia is described from South China: S. uniseta sp. nov. This new can be distinguished two other by following characters: colour pattern, single labial chaeta M, chaetotaxy on terga and ventral tube, unguis with three inner teeth, 15 clypeal ciliated chaetae. Also, first instar for time in present paper, confirms close relationship between Homidia . key to provided.

The family Tomoceridae is among the earliest derived collembolan lineages, thus of key importance in understanding evolution Collembola. Here, we assembled a chromosome-level genome one tomocerid species Tomocerus qinae by combining Nanopore long reads and Hi-C data. final size was 334.44 Mb with scaffold/contig N50 length 71.85/13.94 Mb. BUSCO assessment indicated that 96.80% complete arthropod universal single-copy orthologs (n = 1,013) were present assembly. repeat elements accounted for...

Three new recorded species of genus Homidia were collected from Xizang Autonomous Region, China, in the present paper. Among them, a species, breviseta Pan, sp. nov. , is included This can be identified by having single uninterrupted dark band on central thoracic segment III; 14 macrochaetae abdominal I and seven posterior IV (half segment); very short bothriotricha segments II–IV. It easily discriminated similar its colour pattern, chaetotaxy labium, IV. The first second instar larvae this...

A new species of Collembola, Pseudachorutes cheni sp. nov. from Zhejiang Province, China, is described. It close to P. andrei Weiner & Najt, 1985 Korea and anomalus Imms, 1912 India. However, it could be easily distinguished them other members the genus by structure mandible, maxilla, postantennal organ, unguis dorsal chaetotaxy abdomen.

Formosatettix nanjiensis: Zha & Ding sp. nov. and F. taibaiensis are described from Zhejiang Shaanxi provinces of China, respectively. New synonymy is established: tianmushanensis Zheng Li, 2001 = zhejiangensis Deng, 2019 syn. An updated species key to the genus Tinkham, 1937 Tinkham ER. 1937.
